The admiral fell into an old minekart, which began rolling down the tracks!

(the next part should be sung to the tune of "dry bones")
The barricades connected to the...

Counter weight! The counter weight holds the...

Ramp in place! With out the weight the ramp...

Collapses!

As the admiral neared the end of the track, he saw orcs grinning in hungry delight!

Note: the fire is attached to a rectangular piece which is held down with a technic pin and is attached to a rubber band, so when the cart hits that grey vertical technic piece, the piece rotates and knocks out the pin, and the tension of the rubber band pulls the flames up through the grill, "igniting" the grill. pretty clever if i do say so myself :D
FWOOSH! Admiral Hutton suddenly became a delicious admiral roast for the orcs to feast upon!

So this is my entry for MOCmurder tag. sorry for being so late in posting it, but hopefully you all like it and decide that the wait was worth it.

These next two pictures are the little minekart I built, it took some figuring out, cause i needed it to fit a minifig, but still be approximately 4 studs wide.
I think I found a design that fit the part real nicely.

A nice little waterfall trickles down the cliff wall, wish i had more trans blue pieces.

And a final shot of the entire underground section. I really had fun building the cave part, personally I am impressed with my landscaping skills, but that's just my opinion.
